UPDATE: This plugin is not maintained for a long time now, no use for it any longer. If you think you might need something like it, feel free to drop me a message.
Since there was no plugin for a hamburger-style mobile menu for the Genesis framework, I decided to make one for my sites. You can download it from the WordPress plugin repository.
Also in the plugin, you have the option to make navigation sticky to the top when a visitor scrolls down the page for x amount of pixels. You can choose either the primary or secondary Genesis menu to become sticky.
